Thanks for your interest! It's around $100/spring for a shop to do the install so I was thinking already having the spring on the shock makes it easier for the DIYers out there. I might be completely off base with this which is why I'm doing the thread first to determine if I should go ahead and have the springs removed from the shock.

Some questions I know others have, how much of a drop are they? I'm guessing they are stock shocks, right? How many miles on them?

I got the backs off tonight, tomorrow the fronts! They are the Eibach 38143.140 Pro-Kit and they lower the car 1" in the front and 1.3" in the rear. They are on the car in my sig, if you click on my sig you can see more shots.
If I sold just the springs I would want $150 plus shipping.
The shocks are stock and have around 50,000 miles on them. Everything is great and they handle like they did the day I put the springs on! I've been nothing but satisfied I'm just looking for that next level handling the coil overs will hopefully provide.

Now I'm just looking to sell the springs for $150 since I had to use the perches for the KWs, which I didn't realize. My car is a 2010, but the kit is the Eibach 38143.140 Pro-Kit which is the one Eibach still sells, doesn't matter the year.
